…seeds, and fruits of many plants, where it serves as a herbicide and insect repellent. It can be found naturally in tea leaves, cocoa beans, coffee beans, guarana, and kola nuts. Furthermore, it is added to a range of meals and beverages that have caffeine. This article provides an overview of caffeine and a list of 4 beverages that have caffeine.
A Primer on Caffeine
Caffeine is the most widely ingested psychostimulant in the world. The word “psychostimulant” refers to a substance that stimulates the neurological system. Caffeine is generally regarded as safe by the Food and Drug Administration (FDA). Caffeine use of up to 400 mg per day has not been linked to negative health consequences in healthy people.
One review research found that 300 mg of caffeine per day is safe in healthy pregnant women, while limited data suggests that 1.1 mg of caffeine per pound (2.5 mg per kg) of body weight is safe in children and adolescents. However, studies have had conflicting results, and some persons may have severe side effects at doses less than 400 mg per day. Heart palpitations, anxiety, sleeplessness, and elevated blood pressure and heart rate are among the adverse effects.
Caffeine is added to various meals and drinks to encourage improved energy, alertness, and mood, so you may be ingesting more caffeine than you realize. This is especially essential to be aware of if you have a history of bad coffee side effects. Here are four caffeine-containing drinks.
List of Beverages That Have Caffeine
Coffee
Coffee is a caffeine-containing brewed beverage made from coffee beans, which are a natural source of caffeine. Coffee is revered for its flavor and scent all over the world, and it is eaten for its stimulating effects, which boost energy levels, mood, and alertness. It is debatable if coffee raises the risk of illness. Some research on the link between coffee intake and disease risk have found an increased risk of heart disease, while others have found possible health advantages, such as a lower risk of type 2 diabetes.
An 8-ounce (240-mL) cup of coffee has around 100 mg of caffeine on average. At this level, 4 cups of coffee per day will keep you under the 400 mg caffeine safe limit for healthy individuals. Caffeine levels in coffee goods, on the other hand, can vary greatly. For example, a 16-ounce (475-mL) Grande Vanilla Latte from Starbucks contains 170 mg of caffeine, whereas a Grande Blonde Roast of the same amount contains 360 mg.
Green tea
Green tea is another natural source of caffeine. It is very popular in Asian nations. Green tea includes amino acids like theanine, which have been proven in tests to operate on the hippocampus in the brain and reduce stress in both animals and people. According to a 2017 study, the combination of theanine and caffeine in green tea may boost brain function and cognition, as well as lower anxiety, however further research is needed.
A serving of green tea has about 30 to 50 grams of caffeine, half of the amount in a cup of coffee. The age of the leaf affects the amount of caffeine in green tea. Older leaves have less of the high-energy substance that younger leaves do.
Yerba mate drink
In South America, yerba tea is a popular beverage. It’s produced from the dried, crushed leaves of the large-leafed tree Ilex paraguariensis. Yerba mate, often known as Paraguay tea, is a natural source of caffeine. Experts have lauded it as a heart-healthy beverage with various possible health advantages, including as antibacterial and antioxidant qualities. Yerba mate is also high in polyphenols, which are plant chemicals with anti-cancer properties. The caffeine concentration of yerba mate varies depending on the manner of brewing, ranging from 20 to 180 mg per 8 ounces (240 mL).
Energy drinks
Energy drinks are carbonated, sweetened beverages that are advertised for their capacity to increase energy, mood, and alertness. Energy drinks, on the other hand, are sold as food supplements, are not regulated by the FDA, and are not subject to rigorous testing. As a result, determining the caffeine level of some products may be tricky. According to one research, the caffeine level in energy beverages ranges between 50 and 505 mg. The popular energy drink Red Bull, for example, has 80 mg of caffeine every 8.4-ounce (250-mL) can. Energy drinks, in addition to caffeine, include taurine, an amino acid produced naturally in the brain that has antioxidant qualities.
